Description

The firm anchor of the Align 2.0 foam line — formerly badged Millennium 2.0 — stacks dual-action PCM cooling, high-density gel memory foam tuned for lumbar support, and body-contouring support foam over a green tea-infused base, twelve inches deep.

The tuning holds back and stomach sleepers level while the PCM layers manage temperature swings — engineered foam behavior at a price the engineering does not usually reach down to.

It is the reference point of the 2.0 foam pair; the 14-inch adds two inches of give on the same platform.

Questions & Answers

How firm is the Align Foam 12?

A supportive firm — lumbar-tuned gel memory foam and contouring support foam holding a level platform for back and stomach sleepers.

What sizes and prices does it come in?

Pricing depends on the size you choose — select one above to see its price.

What is PCM cooling?

Phase-change material — layers that absorb and release heat to buffer temperature swings through the night.

Is this the former Millennium 2.0 foam?

Yes — Align is the current name for the 2.0 line formerly sold as Millennium. Construction unchanged.

Does it work with an adjustable base?

Yes — the all-foam build flexes cleanly with adjustable bases.

Frequently Asked Questions

What does mattress-in-a-box delivery mean?

The mattress ships compressed and rolled in a box. Unbox it on your base, let it expand, and it reaches full shape within a day or two. Foundations and bases are sold separately.

Can I try this mattress before buying?

Yes. The Mattress Store inside our Northfield showroom carries floor models across our brands, and you can take the Dream Catcher pressure-mapping test, powered by X-SensorTech — about 7 minutes, 1,600+ sensors — to see which feel actually fits how you sleep.

Do you remove my old mattress?

Ask our team about haul-away when you schedule delivery — we can walk you through the options for your order.

Do you deliver to the Shore towns?

Yes — we deliver throughout South Jersey, from Atlantic City down to Cape May, including Ocean City, Avalon, and Wildwood. White-glove delivery is available (delivery fee applies), or you can pick up at the store.

Do you offer financing?

Yes — financing is available through the Synchrony HOME card. Ask our team about current offers.
